Help with /dev/tty/USB*

I'm new here to the XFCE forums. The netbook that I have has installed Xfce 4.4.2 desktop enviroment. I need help getting my Acer Aspireone model AOA 110 to recognize the usb to serial adapter, this model does not have a 9 pin serial port. While trying to configure the port in GtkTerm, the error I get it is "No valid serial device found in /dev, sorry! You should have at least one of these; /dev/tty/USB*".

I want to use the notebook to interface with a Cisco router control port when I'm asked to do so when I'm running calls. In the past I have used  a laptop with XP and Hyperterminal. The notebook was given to me when my laptop finally gave up the ghost,( He didn't like linux but boy have I been leaning alot!).

Looking around the internet, it was suggested to use GtkTerm in place of Hyperterminal and buy a USB to serial Adapter. After plugging in the adapter and typing lsusb, I get the message;

Bus 002 Device 002:ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port

When I type dmesg I get,

usb 2-2 new full USB device using uhci_hcd and address2
usb 2-2 configuration #1 chosen from 1 choice

Please don't laugh at the next part as I'm still very new to Linux.

I've been trying to follow the advice given on this page:

I've tried typing in the line:

sudo modprobe usbserial vendor=0x067b product=0x2303

however the errors I was getting in dmesg was unknown parameter 'vendor'

Any help would be greatly appreciated.

Re: Help with /dev/tty/USB*

a) what is the output of uname -r?
b) what is the output of modinfo usbserial?

Normally, you should be able to use it right away.
